Overview
The 4296674 is a Cummins EFC-series electronic speed governor for NT855, M11, and K19 diesel engines. It features wide supply-voltage tolerance (16–32 V DC) for harsh electrical environments and an optimised start-up fuel profile to reduce black-smoke emissions on crank.
Key Features
- 16–32V DC Wide Range — Designed for 24V nominal diesel generator electrical systems with built-in reverse polarity protection
- EFC Proportional Control — Precision PWM output for Cummins EFC actuators with configurable gain and stability settings
- 600–9500Hz MPU Range — Universal magnetic pickup compatibility across Cummins, Perkins, Deutz, and other industrial engines
- Isochronous Speed Control — Maintains constant RPM regardless of load (0% droop) for generator frequency stability
- Sealed Electronics — Conformal-coated PCB and IP65-rated enclosure for reliable operation in dusty, humid generator enclosures
- Drop-In Replacement — Direct OEM replacement for Cummins 4296674 with no wiring modifications required
